Speciucation of Letters Patent. Patented June 2S, 1921.

. Application led January 27, 1919, Serial No. 273,412. Renewed November18, 1920. Serial No. 425,032.

To all whom t may concern Be it known that L-"Gumo BLnNIo, a citizen ofthe United States, residing at New York, in the county of New York,State of New York, have invented certain new an'd useful Improvements inFire-Extinguishers, of which the following is a description, referencebeing had to the accompanying drawing/, forming a part hereof.

y invention relates to fire extinguishingv apparatus and has for itsobject to provide a simple, efiicient and inexpensive device for thispurpose which will be always ready for use and can be set in operationinstantly, requires no special skill to put in operation or to use andis adapted to be used with one hand. `A further object of the inventionis to provide a device of this charac-l ter with the fewest possiblenumber of arts, which will not get out of order and will, at all timesbe absolutely tight against leakage.

With these and other objects hereinafter explained in view my inventionconsists in the; construction and combination of parts hereinafterdescribed and claimed.

Referring to the drawings Figure 1 'is' a vertical central sectionalview of a device embodying my invention and Fig. 2 is a top plan viewwith the rod 18 and head 19 removed.

In the drawings v1 indicates the container here shown las formed ofmetal in the form of a cylindrical vessel with. fixed bottom 2.

At its upper end the contalner is provided f with a top 3 firmly securedto it and having a large central opening screw threaded at 4. Thiscontainer may be provided with a handle 5 though for ordinary purposesit will be made of such size as to be readily grasped in the hand and nohandle will be needed. This container is made sufficiently strong towithstand the pressure 4of gas as hereinafter vdescribed and may be madeof heavy glass if preferred. Ifmade of metal it is preferably coated onthe inside with shellac or Iother material which will protect the metalagainst any corrosive action of the liquid in the contalner.

A head 6 is constructed to fit the opening in the top in which it isadapted to be Se.-A

cured by screwthreads 7 tting the screwthreads 4. Thishead is arrangedto carry all the operating parts of the extinguisher. It has on its uper side a central boss 8 whicli-is adaptedp to'lreceive a wrench bywhich the head may be screwed into placeor unscrewed, and has on itsunder side a lcentral boss 9 screwthreaded on its exterior at 10 toreceive the upper end of a receptacle 11 adapted to hold a capsule 12 asherein? after described. Thehead 6 also has at one lside of the bosses 8and 9 a smallopening in terminating inl a pointed end 20. On thev rod 18below the boss 9 is a washer 21 of cork or leather which is held inplace by a nut 22 which is screwthreaded to fit the screwthreads of therod.

Between the head 19 of rod 18 and the to of the boss 8 is arranged aSpring 23 whic acts to force the rod normally upward and .to hold it insuch position in order to keep the pointed end ofthe rod away from thecapsule 12. The' extent to which the rod may be forced outward by thespring is determined by the position of the nutl 22 and the washer 21and by screwing the nut up or down on the rod the position in which theY point o'f the rod is held may be regulated.

The lower end of the boss 9 is faced olf so that the washer 2 1 will fitclosely against it and make with it a liquid and gastight joint. Thereceptacle 11 for the capsule 12 is provided in its sides with openings24 and 25, the upper openings 24 being arranged substantially in linewith the upper end of the capsule 12 and the openings being one oppositethe other so that by looking through .them the position of the point 20relative to the upper end of the capsule may be seen and such adjustmentmade as may be desirable.`

The capsule 12 is of the usual construction of capsules for holdingliquefied or highly compressed carbonic acid gas or other gas or air,lthe top of the capsule being adapted, as -is usual, to be pierced orbroken by the point 20 to release the gas.

In use thecontainer 1 is filled to about` the line 26 with the lireextlnguishing 2. id which iS Preferably. `aie-hieraii'yiim li 2H013)which I have found to. be superior .for fire extinguishing pur oses tothe carbon tetrachlorid common y used `in hand fire, extinguishers, forthe reason among others that it does not attack metal and is a moreeii'ective non-conductor of electricity, a-fact which is of importanceif a fire in which electric light wires o r other wires carrying highcurrents are involved the stream of liquid from a fire extinguisher"sometimes Aforming apath for the current to the injury or even'death ofthe erson using the extinguisher. `Trichlorethy ene is also somewhatless expensive than carbon "tetrachlorid which,however, may be usedin mydevice above described particularly if the interior of the container l,if of metal, is coated with'shellacas above suggested or with asolutionvof glue to which a small v`amount of glucose 'or glycerin hasbeen add- `v`-ed,y or with pyroxylin or any other coating "which Willnot beaected by carbon tetra- A-f"chlorid.

. scribed. to the line 26, a filled capsule 12 is placed in thereceptacle 11 and the receptacle l-fWhen the container has been filledaside'- 5 is-screwed into place on the boss 9, the rod 18 beingpreviously adjusted by screwing the nut 22 up or down as may benecessary. The

i head-6 carrying the capsule in the receptacle 11 andthe pipe 14 is'then inserted in the opening in the top 3 and screwed to place gy meansof a wrench applied tothe boss 8.

he extinguisher may then be. put in its rack or other place close athand for use if needed. When needed to extinguish a fire a blow of thehand on the head 19 drives the pointed end 20 of rod 18 downward againsttheresistance of sprin 23 piercing the softend of the capsule. T espring' at once act-s to Withdraw the point 20 so as to permit freeescape of the gas which flows into the Aspace above the liquid creatinga .high' pressure. The valve 16 may be opened either before or after thecapsule is pierced. When the valve is opened the pressure of thegasdrives the llquid in the container up through the `plipe 14 Vand outthrough the nozzle15 whi y :made'as show n with an interior taper sothat thev liquid dischar d through 1t will be vsprayed instead e vvobeing discharged' in a solid stream.

The nozzle 15 arranged as shown at a angle pointing slightly upwardsothat when the container is inclined so as to direct the streamfrom thenozzle horizontally or down ward, the last of the liquidv will be brouht directly-under the end of pipe 14 so t at practically all of it willbe forced out before the gas can reach the end of the pipe.

The container 1 may be made yof any size desired but as above pointedout is particularlyuseful where made of such size that Vit may begraspedv in one hand and the stream of li uid thus directed by lone handagainst the re leaving the other hand of the user free to pull or ushinflammable or other articles away. y reason `of this adaptability forone hand use without need for use of thev other hand except for aninstant to drive the head 19 down, the device is particularly useful onaeroplanes as wellv as for vhousehold and other general use.

All of the operating parts .being carried by the head 6 can be readilygotten atifor suchV attentions as theymay need at any time. The washer21 -being held against the 4face of the bossv 9 by the spring preventsany evaporation when the charged device is not in use and prevents anyescape of gas around the rod 18 thus insuring that the/full force of thegas will be utilized to force the fire extin uishing liquid out.

n case a first blowon the head 19 should not fracture the end of thecapsule a second blown'iay be struck on it thus insuring a full npeningof the capsule Which is not always secured where a screw rod yis used.The washer 21 should not be of rubber, particularly if carbontetrachlorid is used in the device because of the solvent action of It`is pref,-
